Bolts, mechanical parts, cylindrical threaded fasteners with nuts. Bolt: A type of fastener consisting of two parts, the head and the screw (cylinder with external thread), which needs to be matched with a nut to fasten and connect two parts with through holes. This form of connection is called bolted connection. If the nut is unscrewed from the bolt, the two parts can be separated, so the bolted connection is a removable connection.
According to the force mode of the connection: ordinary and hinged holes. According to the shape of the head: hexagonal head, round head, square head, sunken head and so on. Among them, the hexagonal head is the most commonly used. Generally, countersunks are used where connections are required.
The application is very wide.
There are many names for bolts, and everyone's name may be different, some people call them screws, some people call them bolt nails, some people call them standard parts, and some people call them fasteners. Although there are so many names, the meaning is the same, all bolts. Bolts are a generic term for fasteners. The principle of bolting is a tool that uses the physical and mathematical principles of the inclined circular rotation and friction of the object to gradually tighten the mechanical parts of the object.
Bolts are indispensable in daily life and industrial manufacturing, and bolts are also known as industrial meters. It can be seen that bolts are widely used. The application scope of bolts includes: electronic products, mechanical products, digital products, power equipment, electromechanical mechanical products. Bolts are used in ships, vehicles, hydraulic engineering, and even chemical experiments. Anyway, bolts are used in many places. Just like the precision bolts used in digital products. DVDs, miniature bolts used in cameras, glasses, clocks, electronics, etc.; General bolts for televisions, electrical products, musical instruments, furniture, etc.; As for engineering, construction, and bridges, large bolts and nuts are used; Transportation equipment, airplanes, trams, automobiles, etc. are used together for large and small bolts. Bolts have important tasks in industry, and as long as industry exists on the earth, the function of bolts will always be important.
